Subjective complaints of dizziness or vertigo appear to be relatively common accompaniments of migraine, particularly migraine with aura, and prevalence increases with age. Disequilibrium symptoms have a strong and positive association with the severity of migraine pain. With co-occurrence higher than expected by chance, the relationship either reflects comorbidity or these symptoms may be part of the migraine presentation. With a point prevalence of 15.7%, and factors that link expression both to the intensity of migraine pain and to migraine aura, the authors believe that the true relationship may prove to be the latter.

Presence of NP was associated with delayed treatment of migraine, as indicated not only by higher pain burden at time of treatment but also by delay beyond 30 minutes.

In this sample of women with both MwA and MRM, use of an extended-cycle vaginal ring contraceptive was associated with a reduced frequency of migraine aura and with resolution of MRM. This cannot be extrapolated to suggest that stroke risk in MwA will be similarly reduced. Studies to evaluate this relationship are warranted.
